Message type ACPJMM error

HI experts

I'm getting a strange error while i try to post a goods receipt or goods issue. the message says

receipients missing in Message type ACPJMM ( message B1003)

The Idoc is passed through a ALE layer and the message is assigned with three receipients, either enter the receipients or deactivate the message.

What's wrong in my system? i think this is a BASIS error. Kindly let me know the steps to correct this error.
